The average cost of a mess meal in AIIMS Delhi is around INR 40-50. For vegetarians and around INR 120 for non-vegetarians. Breakfast and snacks are less expensive than lunch and dinner. To name a few
On average, you will spend 200 rupees a day on food. This includes extra snacks that you have in between meals like biscuits or cold drinks. The total comes to around 6000 rupees monthly and 72000 rupees yearly.
The total expenses standing at the end of the month including laundry, ironing, hanging out, and other miscellaneous expenses will stand around INR 8k-10k. I don't think these expenses can be considered high given the fact that the annual AIIMS MBBS Fees is INR 1,389.
